This multicenter, randomized, double-blind, placebo-controlled trial aims to evaluate the effect of mazdutide, a dual GLP-1/GCG receptor agonist, on coronary plaque progression assessed by coronary computed tomography angiography (CCTA) in patients with coronary atherosclerosis and overweight or obesity. The primary endpoint is the change in total non-calcified plaque volume (NCPV) from baseline to week 52. Secondary endpoints include changes in pericoronary adipose tissue inflammation (fat attenuation index, FAI), plaque composition, metabolic parameters, inflammatory biomarkers, and clinical outcomes. A substudy will include 18F-NaF PET/CT imaging.
Coronary atherosclerosis is the principal pathological substrate underlying most cardiovascular events and remains a leading cause of morbidity and mortality. Overweight and obesity are well-established independent risk factors that drive the development and progression of coronary atherosclerotic plaque, and thus represent critical modifiable targets for therapeutic intervention.
Prior studies have shown that GLP-1 receptor agonists (GLP-1RAs) provide hypoglycemic, weight-loss, and cardiovascular protective benefits. Mazdutide, the first approved GLP-1/GCG dual receptor agonist, combines GLP-1-mediated insulin secretion and appetite suppression with GCG-driven energy expenditure. Phase III trials have demonstrated robust glycemic and weight benefits, along with reductions in hs-CRP and liver fat. Given that dual-receptor activation yields more robust metabolic improvements than single-receptor agonism, mazdutide may possess greater potential than GLP-1 monotherapy in suppressing coronary plaque progression.
Therefore, we propose a multicenter, randomized, double-blind, placebo-controlled trial to evaluate the effect of 52 weeks of Mazdutide treatment on CCTA-assessed non-calcified plaque volume (NCPV) in patients with coronary atherosclerosis and overweight or obesity.
PET-CT substudy: A subset of eligible patients will be enrolled into a sub-study, we aim to evaluate the efficacy of Mazdutide on plaque inflammation assessed by 18F-NaF PET/CT.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
History or evidence of the following :
Use of the following medications or treatments prior to screening :
Laboratory test results meeting any of the following criteria at screening (repeat testing within one week is permitted if there is a clear reason, and the reason for retesting must be documented by the investigator)
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Started Sep 2026 (actual). Primary completion is estimated for Dec 2027, 15 months after the start.
Of 190 non-industry phase 4 interventional studies under Obesity, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 52. This study's planned 15 months is below that.
Counting every sponsor, half of 210 studies reached it within 31 months; a quarter within 15 and three quarters within 51.
How these figures are worked out, and which studies are left out of them.
